Hi Mark,
Thank you for your reply, but could you explain more? For example, if
I search a very hot key word (not a, or o ), and the tweet flow is
5000 tweets/min. Does this mean that I only be able to receive
2000tweets/min because the restriction? what about the other 3000
tweets? Will they be delayed or just discarded?


Cheers
Lawrence
